A distinctive complication with balloon-expandable (BE) THV platforms such as the Edwards Sapien (Edwards Lifescience) is the possibility of balloon rupture during THV deployment. Balloon rupture is a rare occurrence that can result in stroke due to fragment embolism, incomplete THV expansion, and/or vascular injury upon retrieval of the balloon. Careful evaluation of preoperative computed tomography is essential to identify high-risk cases. While annular and left ventricular outflow tract (LVOT) calcification are widely acknowledged as common risks for balloon injury, it's essential to note that balloon injury can manifest at various anatomical sites. In this review, we discuss the mechanism behind balloon rupture, methods to identify cases at a heightened risk of balloon injury, approaches to mitigate the risk of rupture, and percutaneous retrieval strategies.

经导管主动脉瓣置换术期间球囊破裂

Edwards Sapien（Edwards Lifescience）等球囊扩张 (BE) THV 平台的一个独特并发症是 THV 部署过程中球囊破裂的可能性。球囊破裂是一种罕见的情况，由于碎片栓塞、THV 扩张不完全和/或球囊回收时血管损伤，可能会导致中风。术前仔细评估计算机断层扫描对于识别高危病例至关重要。虽然环状和左心室流出道 (LVOT) 钙化被广泛认为是球囊损伤的常见风险，但必须注意的是，球囊损伤可能出现在不同的解剖部位。在这篇综述中，我们讨论了球囊破裂背后的机制、识别球囊损伤高风险病例的方法、降低破裂风险的方法以及经皮取出策略。
